5.2.8. Winds Aloft
The Winds Aloft screen displays the forecast wind speed and direction at the selected
altitude above MSL on a basic weather map (
Figure 5-63
). Winds are depicted as barbs
up to a map range of 500 nm; for map ranges of 1000 nm and above winds are not
rendered and the XM Receiver Status is displayed (
Figure 5-64 ).
When the map range is below 500 nm the wind direction is depicted by wind pointer
lines extending upwind from the reporting weather station (the small dot on the
bottom of the shaft). Wind speed is depicted by pennants or short lines (barbs) on the
upwind end of the shaft. Each short barb represents 5 kts, each long barb represents
10 kts and a pennant represents 50 kts. Wind pointer lines can depict winds up to 190
kts (3 pennants and 4 long barbs). The Winds Aloft legend provides a depiction of each
type of measurement (
Figure 5-65
).
